Some progress

With no luck trying to resurrect the server, I pulled the disks out and put them into an external cabinet with a USB3 interface. Plugged it into my Windows computer, which didn't know what to do with it. Luckily, I had Ubuntu running in a virtual machine on it, and it immediately mounted each partition so I could get to the data.

So, now all the data (and code) is transferred to the new server, and using Docker I will get site by site up again - load the data into a database, and start each site in its own container. Running into some snafu around session handling vs. new code, which makes the libraries on the old server show their age and lack of maintenance. I was able to get some sites running by "faking it" by simply running the old code and their old libraries as well in the Docker container, but that is not terribly future-proof... So some of the sites will require some change in the session handling code to get up to speed with current libraries, others may not. For now I'll likely be too busy until after Christmas Eve before I can get to the next few sites, but hang tight - we'll get there. :)
